To all whom it may concern.'

Be it known that l, FRED SCARR, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in the Stud Members oi' Stud-and-Sooket Fastening Bevices, of which the following is a speciiication.

This invention relates to fastening devices comprising a socket member having grasping jaws of a yielding character, and a stud mem ber adapted to be inserted in thesoclret member and engaged with the jaws, the said members being provided with means for attachment to the two parts to be sep'arahiy connected by the fastener. Y

The invention relates particularly to the stud member of a fastening device of this character, and has for its object, iirst, to enable the stud member to be so firmly engaged with the jaws that any attempt-to disengage it from the jaws by a direct or outward pull substantially lengthwise of the stud member will increase the firmness of engagement, and .j

prevent disengagement or separation of the two members.

'lhe invention also has'for its-object to provide certain improvements in the construction of the stud member whereby the'eX- pense of construction is reduced to the minimum.

The invention consists in the improvements which l will now proceed to describe and claim. Of the accompanying drawings, forming a part of this speciiication,-Figure 1 represents a side elevation of a stud member em bodying my invention, the socket member being shown in dotted lines. Fig. 2 represents an end elevation of the stud member,

showing in dotted lines the yielding jaws ot the socketmember. Fig. 3 represents a top plan view of the stud member, the jaws being sh'own in dotted lines. Fig. i represents a iront view of the socket member which is employedwvith the stud member. Fig. 5 represents a section on line .55 of Fig. 3. Fig. 6 represents a section on line 6-6 of Fig. 5. Fig. 7 represents a perspective view oi the stud member, its base being broken away, showing the jaws in engagement with the shoulders of the stud member. Fig. 8 represents a view showing the jaws tipped to cause their disengagement from the shoulders of the stud member.

The same letters of reference indicate the same parts in all the gures.

ln the. drawings, 12 12 represent the jaws of the socket member with which my improved stud member, forming the subject of this invention, is used, the said jaws being preferably the end portions of a Wire member which is bent substantially 'as indicated in Fig. 4, to form the said jaws, and a marginal ortion connecting the jaws, each jaw being lree at one end. The jaws are contained in a casing 13 having an orifice 14 for the stud member, and suitable means for engagement with one oi the two parts which are to be connested by the fastening device, the said parts being, for example, the portions of a glove which form the edges of the wrist opening, or one of said portions may be the Acurtain oi a carriage top and the other the frame work of said top. In fact, the fastening device to which my invention relates is capable of a variety of applications, and is not limited in this respect'.

In Fig. v1 the part to which the socket member is attached is indicated by dotted lines, and is designated by the reference numeral 16. .I will hereinafter refer to the part 16- as the holder for the socket member, it being understood that this holder may be a part of a glove, carriage curtain or any other device.

The jaws 12 are free to move toward and from each other, and they extend across the opening 1l, as shown in Fig, 4. They are normally held relatively close to each other by the resilience of the wire, and are adapted to be sprung outwardly or pressed apart by the insertion of the stud member between them.

' 22 represents the stud member, which as here shown is rovided with a base 23 adapt-v ed to be attac ed in'any suitable way to an inner part, such as 'the part of a glove which is overlapped by the socket holding part 16, or the frame of a carriage top or any other article. The 'I'orm of the outer portion of the stud member is such that it is adapted to be inserted between the ,jaws 12 12, and to displace said jaws outwardly by passing be tween them,the sides 27 of the stud member at the outer portion thereof being therefore formed to give the stud member a wedgesha ed outer end.

rIllie'sides of the .jaws are rovided with shoulders 25, which are forme to engage the jaws 12, and prevent the separation of the socket member from the stud member by a pull or by pressure on the socket member in r' shoulders 25 are the outer sides ol' diagonal or undercut grooves formed in the sides oi".v

the stud nzeinlwr for the reception ol the i jaws, the inner sides lo of said grooves being end is swung inwardly toward `instead of being in alincnicnt with diagonallydisposed so that they are adapted to serve as ja\\'displaiing lares when the socket inenihei' is tippt-d, so that its upper the hase 23, and its lower end is swung outwardly.

nelly formed or undercut, so that their outer edges overhang their inner edges, the slioul i ders 25 bein T inclined in o i )osito directions b I each other. This formation oi the shoulders nicreasesth'strenfrtli olY their eiweeenient with D v l-' the uws and enables there to enr-*afro the d I 1 Alt: n jaws niore ininly' than would be rnc case it the shoulders 25 were in ahneineiit with each other. vOwinuT to this dragonal'iorniation of s tliesliouldors 2o, any`atteinpt to remove tire vsocket member troni the stud .member in the direction indicated by the arrows :c fc, will presshe jaws inwardly toward :h other, so that the iiranngss of theiiiengagei ent with the stud member. is increased by a direct out- `Ward `pull in' pressure on the socket member.

The sigles 27 2.7 oi the outer portie-n the stud member are oppositely inclined crosswise of thostud, the said sides being so shaped that the outer portieri of tl stud member is wedge sha )ed in cross section, as shown in lfig. 2. rllie sides 27 constitute jaw-displacing faces which are adapted to ct either alone or in connection with the faces 26 in forcing the jaws outwardly away from each other when the socket member is tipped or inclined. The jaws i2 may be readily disengaged from the stud member by' giving the j aws and the socliet n'ieinber a tipping movement by swinging outwardly the lower end oi the socket member andY at the saine time swinging inwardly its upper end.

When this is done the jaw-displacing faces 26 27 act to separate or force outwardlj;v the jaws until they are disengaged from the shoulders '25, and are therefore free to slip oil from the outer portion ot the stud member. This movement of the socket member may be conveniently eilected by gras )ing the lower edge of the part or holder lo, and tip- Ping' it outwardly and upwardly The stud member 22 is' preferably formed solid metal.

i f l i l l j the Ylirin ness @raras are formed by forcing portions of they sheet metal sides inwardly, and side-connecting portions integral with the sideportions, and constituting the top and bottom edges lof tho stud. This construction decreases the weight of the stud and the cost of making it, compared with a stud which is made of The base 23 of the stud ineinbei' is also preferably made et sheet metal, and integral with the sides and side-connect- 'i'lhe jawrngaging shoulders 25 are diagoi in portions of the stud, the marginal portion oi" the base being provided with a stii'fening i'iange 23() which is bent from the base, and

2 bears on the part towhieh the stud is attached. The orifices in the base for the reception of the attaching members may be l surrounded by inwardly projecting flanges 231.

It is obvious that the members of my iinproved fastening device may be of any desired size, and'thus adapted for the Work required, a glove fastener, of course, being niuch smaller than a fastener for carriage curtains.

i claim:v y

l. in a stud and socket fastening a stud member at its outer portion, and diagonal or undercut grooves in its sides for the reception of socket jaws,v the grooves extending inward i'ioni said inclined faces, and being arranged so that a direct outward pull on jaws in said grooves will force the jaws toward each other and thus increase the iirinness of their engagement with the stud member.

2. A fastening device comprising a socket member havin separable resilient j-aws normally held yie dingly in their operative position, and a stud member having inclined sides or faces at its outer portion, and having diagonal or undercut grooves for the rece tion of said aws extending inward from said inclined faces, and arranged so that a direct outward pull Aon the jaws will press them inwardly toward each other, and thus increase of their engagement with the stud member.

in testimony' whereofl I have ailixed my signature, in presence of two witnesses.
